Just want to let you know, I'm aware of the email issue and I'm currently working on it. Not sure when I will have a fix in place, but wanted to keep y'all updated.
Had a few minutes and went in and did some work to the email system. I'm no longer using rc-help specific emails, I'm going through the server, however the email will show to come from rchelp.com@gmail.com. Wanted to post this so you know this is a legit email at this time so that y'all can get updates and I can turn on email registration again.
Please note, any email from this website coming from rchelp.com@gmail.com will likely fall into your spam folder for the first email. If you set this address as a trusted address, you should receive all others without issue. Just be sure to check the spam folder periodically for emails from the site for a bit.
